Regarding the recent study published by the National Health Research Institutes, "Long-term use of vitamin D3 in the elderly may increase the risk of dementia," which has caused panic among people who are currently using vitamin D, we would like to provide an explanation：
Vitamin D can be divided into inactive and active. Currently, all commercially available vitamin D3 nutritional products, including Liquid P&B Vitamin D3, belong to the Inactive vitamin D. It does not have any function in itself. It is effective only by providing raw materials and converting them into calcifediol and calcitriol (active vitamin D) according to the body's needs.
However, this study by the National Health Research Institutes actually used data from the National Health Insurance database to identify people who were using prescription active vitamin D (the drug is called calcitriol) and to observe the risk of getting Alzheimer's disease in the future. Active vitamin D is different from the inactive D3 used by the general public. It can easily cause side effects such as hypercalcemia and vascular calcification. It is also a prescription drug and needs to be used with caution.
Therefore, research reports directly confuse the prescription drug active vitamin D with the inactive vitamin D commonly used by the public, which is inappropriate. If the vitamin D concentration in the blood test is insufficient for the general public, they should supplement with inactive vitamin D3, which is highly safe and will not have any side effects at the appropriate dose.
- Liquid P&B Vitamin D3 is the only inactive vitamin D on the market that has complete batch-by-batch safety reports, and it is purchased and used by more than ten medical centers in Taiwan. Please feel free to use it.
